A person I've never met before in my whole life asked me "Is that a new suit?" Apparently he was thinking the only reason I would wear of suit is that I just got one as a gift or something and wanted to show it off.

About a month ago, a person I see pert near every day says to me "Special occasion? Got a suit on today!" I have a suit on every day that I'm at the workplace (with certain fairly rare exceptions).
